Discarding cards that don't improve your hand is crucial, but it's also critical to think about what your opponents might require. Avoid discarding cards that could aiplay store alld an opponent in finishing their sets or sequences if you observe that they have been regularly selecting cards from the discard pile. If your opponent is picking up 3♠ from the discard pile and you have two 4♠ and one 5♠, for instance, it might be wise to hold onto your 4♠ until you can tell if they are building towards a sequence.
